Abstract
A new example of the application of the Bijovet method enabled–unintentionally–conclusions to be drawn about the configuration of (+)-tartaric acid. The (–)-2,3-butanedithiol obtained from (+)-tartaric acid gives a diastereomeric mixture with racemic 1. The chromatographically separated component 2 proved to be a product of (S,S,S,S)-1 and (R,R)-2,3-butanedithiol according to Bijvoet; hence, it follows that (+)-tartaric acid has (R,R)-configuration.
